Task control block.

In single-task blocks of the dual-task part, an asterisk, which served as task-irrelevant S1, appeared to the left of the fixation cross, followed by a task-relevant S2 to the right of the fixation cross after a random SOA of 100 ms or 600 ms. In dual-task blocks, the asterisk was replaced by a task-relevant S1. Process Control Block (PCB, also called Task Controlling Block, [1] Task Struct, or Switchframe) is a data structure in the operating system kernel containing the information needed to manage a particular process.
